Covestro DUREFLEX® PS5400 TPU
Categories: Polymer; Thermoplastic; Polyurethane, TP
Material Notes: Characterization: The Dureflex PS5400 Series is a family of aromatic polyester polyurethane film/sheet products.

Properties/Applications: Desmotherm® 2170 is used primarily as the binder in one-component stoving polyurethane systems for highly flexible primers, intermediate coats, primer surfacers and thin coil-coating primers. Being a self-crosslinking stoving urethane resin, the product contains the amount of polyol required for crosslinking as well as the hardener. The film properties can be modified by combination with various polyesters from the Desmophen® and Alkynol® ranges, amino resins and flexibilisers. The main field of application for systems based on Desmotherm® 2170 is as primer surfacers in automotive OEM finishing. When formulating coatings with Desmotherm® 2170, the temperature should not exceed 60 °C otherwise the crosslinking reaction will begin.
